Splitting an input String

Question

I've the following Query String,

QUERY 192.168.1.0 0 2016-08-25 18:32 2016-08-26 18:31

I want to split it into 5 string objects such that 2016-08-25 18:32 and 2016-08-26 18:31 are parsed as one object.

String[] arr = str.split(" ");

Splits the String into 7 strings splitting the dates. I'm not sure how to do it using regular expressions using Java. Any help appreciated.

Answer 1

as long as the positions of the items are static, simply manipulate your output array after the split:

String sdate = arr[3] + ' ' + arr[4];
String edate = arr[5] + ' ' + arr[6];

if needed, make a new array:

String[] arr2 = {arr[0], arr[1], arr[2], sdate, edate};

good luck!

Answer 2

实现上述目标的另一种简便方法是使用regex将字符串按空格分隔到新行上。

str.replaceAll("\\\\s", "\\n")

Answer 3

You totally don't need a RegEx here. Parsing a string with regex is a rather complex process, and in your situation where you have static positions in string and can just concatenate parts - regex is an obvious overkill.

And by the way, regexes almost always make your code much less readable. So with regex here you will end up with a lot less readable and performant code.

Vote against RegEx.
